Traditional metrics driven audits anchored in technical checklists and quantitative controls frequently overlook the human centric and organizational vulnerabilities that underpin many breaches. This paper delivers a comprehensive systematic review of 23 peer reviewed research papers, industry reports, and regulatory guidelines, augmented by a thematic analysis of survey data from 25 U.S. health systems surveyed anonymously. We identify a clear paradigm shift from purely quantitative assessments toward qualitative audit methodologies that probe governance structures, stakeholder behaviors, and cultural dynamics. Building on these insights, we introduce an intelligent agent enhanced qualitative Information Systems audit framework. The model integrates semi structured interviews, policy and artifact reviews, direct observation, and AI driven meta classification to translate nuanced findings into structured risk profiles. Audit teams now blend on site ethnographic techniques with remote AI assisted analytics, enabling real time detection of emerging threats. Our analysis uncovers five core themes: policy practice alignment, behavior-based risk indicators, continuous control monitoring, cross functional governance, and adaptive remediation loops, which traditional tools fail to capture. Case studies demonstrate that institutions applying this hybrid framework achieved a 46 percent reduction in unauthorized access events, faster incident response cycles, and a stronger regulatory compliance posture. We conclude that a flexible, culturally attuned, and technology augmented audit strategy is essential for resilient healthcare cybersecurity. Future research should explore longitudinal impacts of AI enabled qualitative audits and the scalability of this approach across diverse clinical settings.

Despite the widespread use of encryption and secure socket layer (SSL) technologies, traditional single-factor authentication methods such as static passwords and Card Verification Value (CVV) codes remain susceptible to cyber threats, including phishing, data breaches, and credential stuffing. This paper proposes the implementation of One-Time Password (OTP)-based Two-Factor Authentication (2FA) as a scalable and effective mechanism to enhance the security of card-based transactions in the U.S. banking system. By combining a user-known credential with a dynamic, time-sensitive OTP, the study presents a robust authentication framework designed to reduce unauthorized access and transactional fraud. The discussion draws on a comprehensive review of current fraud trends, limitations of existing authentication models, and a conceptual OTP-integrated security architecture adaptable to banking infrastructures. The paper also considers technical feasibility, user experience implications, and regulatory compliance. Findings offer practical insights and implementation strategies to support U.S. financial institutions in mitigating fraud risks while maintaining accessibility and usability for consumers.

This review delves into the nuances of business development strategies in these markets, while also exploring the consequential economic ramifications. Historically, business development strategies in emerging markets were anchored on direct investments and exports. However, with the pace of globalization and the rise of digital technologies, there has been a marked shift in strategies. The review reveals that these strategies now prioritize understanding the local culture, forming beneficial partnerships with local enterprises, adapting to the technological landscape, and innovating products and services in line with local needs and preferences. Entry modes into these markets are no longer one-size-fits-all. Companies are seen to be leveraging a mix of wholly-owned subsidiaries, franchises, joint ventures, and even digital- first entries to navigate the complex terrains of emerging markets. Local partnerships, especially, have emerged as a vital tool for foreign businesses. Partnering with local entities not only aids in navigating the regulatory and cultural landscape but also in accessing established distribution networks and building trust amongst local consumers. The adaptation of products and services to resonate with local consumers, driven by meticulous market research, has played a pivotal role in the success of many global brands in emerging markets. Furthermore, the technological boom, especially in sectors like e-commerce, fintech, and telecommunication, has opened new avenues for businesses. More direct economic implications include influences on the Gross Domestic Product (GDP) and foreign direct investments. Emerging markets with welcoming business policies have seen substantial inflows of capital, bolstering their economic growth trajectories. A total of 55 research papers were reviewed for this study and the methodology used for the study is the systematic review method using thematic analysis, where recurring themes, insights, and patterns were identified and categorized. However, it is not without challenges. Cultural nuances, regulatory bottlenecks, geopolitical uncertainties, and financial unpredictabilities (like currency fluctuations) can pose significant barriers. Also, while entering an emerging market might be easier now than before, sustaining business operations and managing competition, both from established global players and rising local enterprises, is a continual challenge. In conclusion, the study positing that businesses need to adopt a flexible, localized, and technology-driven approach, while policymakers in emerging economies should focus on creating a more conducive environment for foreign businesses. As we move forward, further research is essential to keep abreast of the evolving trends and challenges in this dynamic nexus of business development and economic growth in emerging markets.
